Malaysia Airlines flight MH370: all passengers and crew being investigated

At a press conference in Kuala Lumpur, Malaysia's Transport Minister
Hishammuddin Hussein says that 25 countries are now involved in the search
for the missing plane and that the pilots, passengers and crew are all being
investigated

Malaysian police are investigating the personal, political and religious backgrounds of the pilots, crew and passengers of a missing jetliner, Malaysia's Transport Minister said on Sunday, as they try to work out why someone aboard flew the plane hundreds of miles off course.

The government also appealed for international help in the search for the Malaysia Airlines plane across two corridors stretching from the Caspian Sea to the southern Indian Ocean, diplomats said.

No trace of the Boeing 777-200ER has been found since it vanished on March 8 with 239 people on board, but investigators believe it was diverted by someone who knew how to switch off its communications and tracking systems.
